The Wacker Neuson Cylinder Head is a genuine OEM component designed for the DPU45Yeh US and DPU40Yeh US reversible plate compactors. As a factory-sourced part, it is manufactured to the exact tolerances and material specifications required by Wacker Neuson for these machines. Sourcing the correct cylinder head by part number ensures a direct, reliable fit with no guesswork on compatibility. If your compactor is showing signs of head failure — loss of compression, overheating, or oil leaks — this is the verified replacement part for those models.
Key Features
- OEM Combustion Integrity — Manufactured to Wacker Neuson's exact sealing surface tolerances, ensuring correct compression ratio and combustion chamber geometry critical to engine performance.
- Direct Bolt-On Replacement — Matches the original mounting pattern and port alignment for the DPU45Yeh US and DPU40Yeh US, so it installs using standard procedures without modification to ancillary components.
- Verified Fitment for DPU Reversible Plate Compactors — Confirmed compatibility with the DPU45Yeh US and DPU40Yeh US series, covering both model variants by part number 5100066579.
- Restores Full Engine Output — A correctly seated cylinder head maintains the compression needed for consistent ignition and full power delivery — a worn or cracked head causes misfires, overheating, and progressive engine damage if left unaddressed.
- Fuel and Emissions System Compliance — The OEM cylinder head preserves the original combustion chamber volume and valve seat geometry, keeping the engine within its designed fuel consumption and emissions parameters.
The cylinder head sits at the top of the engine block and seals the combustion chamber, housing the valves that control the intake of air-fuel mixture and the exhaust of combustion gases. It works in conjunction with the head gasket to maintain compression pressure — without a sound seal, the engine loses power, runs rough, and can overheat rapidly. A cracked, warped, or worn cylinder head compromises every engine cycle and, if ignored, can lead to broader internal engine damage that far exceeds the cost of a straightforward head replacement.
